Custom Carbon Fiber 364 Ktm Exhaust for KTM 390 K21
$70.71 Original price was: $100.71.Current price is: $70.71.
Made-to-order exhaust tips for the KTM 390 K21 - carbon fiber, stainless clamps, worldwide shipping and a 12-month warranty against manufacturing defects.
Fitted to the KTM 390 K21 to replace the dull factory outlets with a pair of finished tailpipes.
It weighs a fraction of the steel or plastic original, without the flex you get from a thin fiberglass copy.
Fits: KTM 390 K21
Sized to slide over the standard pipework of the KTM 390 K21, with a stainless clamp that tightens onto the original outlet.
Cut the old tips free if welded, slide these on, tighten the clamps evenly and check the tips sit level – around 30-45 minutes.
Aftermarket exhausts often have a larger pipe diameter – measure yours before ordering so the clamps fit.
Weave, finish and edge treatment are all chosen when you order: glossy 3K twill is the default, while matte, forged carbon, coloured clear coat and carbon-kevlar hybrids are produced on request.
- 3K twill, 6K twill, plain weave or carbon-kevlar hybrid
- Coloured tinted clear coat (red, blue, yellow)
- Logo application or badge cut-outs on request
- Gloss, matte, satin or forged carbon finish
A ceramic or wax coat once a season is all this needs – the clear coat handles UV, but it is not a scratch-proof layer.
Because the tooling is in-house, changes that a trader would refuse – a different weave, a logo under the clear coat, a slight trim to clear a roll cage – are normal work for us.
Every unit is checked against a photo checklist – pinholes, weave alignment, mounting-hole position and clear-coat flow – before it is packed.
OEM and private-label work is welcome: your part number, your logo, your packaging, with an NDA if you need one.
Made to order in our workshop, typically 10-15 business days before it ships worldwide with tracking, backed by a 12-month warranty against manufacturing defects.
In the box: tip set, stainless clamps and a fitting card.

FAQs
Does this exhaust tips fit the KTM 390 K21?
Yes. The tooling came off an original KTM 390 K21 part, so the bolts and clips line up the same way. The one thing worth checking is the body style: sedan, coupe and estate versions of the same model can use different fixings.
What is it made from?
Carbon fiber, laid up by hand, vacuum bagged and autoclave cured in our own workshop, then finished with a UV-stable clear coat. It is not a hydro-dipped or printed film.
Do I need to drill or cut anything?
Most owners do this at home in about 30-45 minutes with stainless clamps and ordinary hand tools – the original fixings are re-used, so nothing needs welding or painting afterwards.
How long until it ships?
Each part is made after you order it, so allow 10-15 business days in production before dispatch. Express DHL, UPS and FedEx options are available, and tracking is sent as soon as it leaves the workshop.
Can you make it in a different finish or colour?
Yes. Gloss, matte, satin and forged carbon are all available, along with tinted clear coats and 3K, 6K or plain weave. Logo and emblem application under the clear coat is possible on most parts.
Do you offer wholesale or OEM pricing for bulk orders?
Yes – one piece is fine for a sample, and the same mould runs batches of 50, 200 or 1,000+ pieces. OEM and private-label work is welcome with your part number, logo and packaging.
